Modern lenses tend to be large and expensive, with multiple glass elements combining to minimise optical aberrations. But what if we could just use a cheap single-element lens, and remove those aberrations computationally instead ? This is the question scientists at the University of British Columbia are asking, and they’ve come up with a way of improving images from a simple single element lens that gives pretty impressive results.

There’s nothing on earth like a genuine, bonafide, electrified six-car monorail. Or a one-car monorail with a propeller, or a high-speed rail plane, or even an amphibious monorail that can go from the elevated track right into the water. Some of these concepts were doomed from the start, some never got enough support to get off the ground and others still stand today.

Mountain Monorail with Propeller, 1936

This fanciful concept illustrated by Kikuzo Ito in 1936, was invented by an American. The airplane propeller and tailfin keep the small car upright as it rides along the track in the mountains. An extra set of wheels extend from the sides to provide stability when it comes to a stop.

Wuppertal Schwebebahn, 1901-Present

While most early monorail systems either never made it past testing stages or were dismantled soon after construction, the Wuppertal Suspension Railway in Wuppertal, Germany remains in operation after over a century. It was initially designed to be sold to the city of Berlin; the first track opened in 1901. The cars have been replaced over the decades, but since then, the monorail line has been closed just once. It moves 25 million passengers each year.

Bennie Railplane, 1930

The propeller-driven Bennie Railplane, designed in 1930 by George Bennie, was a prototype that aimed to solve the problem of more economical and rapid transport via a high-speed monorail link from London to Paris. A short test track was built in Glasgow, Scotland, but the economic troubles of the ’30s doomed the project. The test track hung around, rusting and abandoned, through the 1950s.

Boyes Monorail, 1911

The test track for the William H. Boyes Monorail was built and demonstrated in 1911 in Seattle, Washington, with wood rails and an estimated cost of about $ 3,000 per mile. When it opened, the Seattle Times proclaimed, “The time may come when these wooden monorail lines, like high fences, will go straggling across country, carrying their burden of cars that will develop a speed of about 20 miles per hour.”

Amphibious Monorail, 1934

Twin amphibian cars zoom from the desert into the open sea in this concept, dreamed up by the Soviet Government and featured in Popular Science in 1934. The idea was that the cars, which could reach up to 180 miles per hour, could travel three monorail lines totaling 332 miles in length in order to tap mineral wealth in Turkestan. They were reportedly tested in Moscow.

“The cars would be equipped with Diesel-electric drive, and each would carry forty passengers or an equivalent freight load,” explained Popular Science. “Where the longest of the projected routes crosses the river Amu-Daria, a mile and a quarter wide, it is proposed that amphibian cars be used. On arriving at the shore the cars would leave the overhead rail and cross the river as a boat. Soviet engineers are reported already surveying the route.”

As part of the continuing celebration of its 125th anniversary, National Geographic once again features Steve McCurry’s famous ‘Afghan Girl’ photograph on the cover of October’s ‘The Photography Issue’. Along with the new issue, National Geographic has launched some supporting content, as well as a new blog called Proof, offering ‘new avenues for our audience to get a behind-the-scenes look at the National Geographic storytelling process.’

How much money do you need to keep your photographic creativeness high? $ 1000? Or maybe $ 3000? Sure, there are quite a few things that cost that much and even more–and they are strong boosters of the creative process though unfortunately not a panacea. Having their eyes fixed on premium lenses and bodies, photographers often oversee many useful things that can Continue Reading

Mount adapters are incredibly useful for their ability to make lenses from one manufacturer usable with camera bodies from another. But do they have any impact on image quality? LensRentals’ Roger Cicala, not one to take manufacturer’s claims at face value, investigated. Knowing that slight mis-alignments between a lens and even its native mount can cause softness in images, the added complexity with a lens adapter in the mix seemed likely to cause more problems. His findings are indeed interesting.

This week I had a number of readers email to ask about the topic of ‘blend modes’ in Photoshop. So I thought I’d see what our friends at Phlearn have on the topic with their great videos. Here’s a great introduction to the different types of blend modes in Photoshop:

It started with a single person painting one public staircase, but when city workers of Istanbul, Turkey covered this brightly-colored street art with dull gray paint, citizen activists picked up brushes in rapid response. Thus escalated an isolated incident into a quiet but powerful city-wide campaign mixing politics, graffiti and beautification.

Aged 64,local retired engineer Huseyin Cetinel spend reportedly $ 800 on paint simply to make the steps in his area more attractive – he notes that nature is colorful, and suggests simply that cities can be as well.

As images of his work began to go viral online, many viewers saw it as a call for equal rights – a political statement. When the municipality painted the original stairs over (then initially denied doing so, adding to the confusion), that act was perhaps inevitably interpreted through a polarizing lens as well.

Twitter and Facebook were awash with calls to color other sets of stairs around the hilly city, and a quiet war fought with guerrilla art began … the city whitewashing (or gray-painting) newly-colored staircases as people kept on recoloring them, before finally agreeing to let the steps be painted as the citizens wished.

As interviewed by the New York Times, local financial adviser Nalan Ozgul sees a larger lesson in these events: “There has been some movement in the society, a social uprising together with the Gezi Park protests, and this is just an extension of that spirit. The fact that the government-run municipality first denied having painted over the stairs, then agreed to paint them back in color, shows how desperate and indecisive they are about their policies.”

Alternatively, perhaps this strange story shows the everyday tensions between ordinary people and relentless bureaucracies as much as it says anything about the activist citizens and imposing governments of a particular time and place, but the effects are certainly colorful no matter how you look at them (Images via Instagram photographer sumrue and Twitter users @durmusbeyin, @demishevich, @verbikerem and @ozgelu)
